UNITED STATES PATENT OFFICE.

HENRY W. ROSE AND JAMES O. HICKS, OF VICTORIA, TEXAS.

SCREW Application filed February To all whom it may concern:

Be it known that we, HENRY WV. ROSE and JAMES O. HIoKs, citizens of. the United States, residing at Victoria, in the county of Victoria'and State of Texas, have invented certain new and useful Improvements in Screw Drivers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to Which it appertains to make and use the same.

' The present invention has for its ob ect the provision of a screw driver which admits of the holding of a screw when placing the same in position or removing the same from a place difficult of access, the tool being of such construction as to adm1t of its ready engagement with or disengagement from the screw.

Other objects andradvantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, var ous changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the application- Figure l is an elevation of a screw driver embodying the invention, showing the relation of the parts when holding or gripping a screw,

Figure :3 is a reverse side View of the tool, the members being spread,

Figure 3 is a section on the line 33 of Figure l, and

Figure 4: is a sectional detail on the line 1-4 of Figure 1.

Corresponding and like parts are referred to in the following description and desig nated in the several views of the drawings byv like reference characters.

The tool comprises similar members 1 and which cross and are pivoted at the point of crossing, as indicated at 3. The gripping ends of the members 1 and 2 terminate in nibs l which are inwardly deflected so as to grip opposite sides of the head of a screw 5, as indicated most clearly in Figure 1. The opposite ends of the members 1 and 2 closed. lVhen closing DRIVER.

terminate in eyes 6 which are. adapted to receive the thumb and finger of the hand in substantially the same manner as the blades of a pair of scissors or shears. A blade 7 is disposed between the jaws of the members 1 and 2 and is mounted upon pivots 3. The blade 7 constitutes the driver proper and is of such relative length that its point-terminates short of thenibs 4, whereby, in practice, when the point of the blade 7 enters the slot in the head of the screw,- the n1bs 4 grip opposite sides of the head, whereby to retain the screw in place, as indicated most clearly in Figure l. I

A ratchet mechanism is provided to. hold the members in closed position, the same consisting of inner projections Sand 9, the projection 8 terminating in a lateral tooth l0, and the projection 9 being formed on the side facing the projectio .8 with a plurality of teeth 11 to coact with whereby to hold the members 1 and 2 when the members, the tooth 1O rides over the teeth 11 and engages with a selected tooth 11 and retains the members 1 and 2 in the required adjusted position. The members 1 and 2 are released by a relative lateral movement of the eyes 6 which separate the tooth 10 from the teeth 11.

\Vhat is claimed is:

A tool of the class described consisting of relatively movable crossing levers forming opposed jaws to jointly engage a screw at their work ends, a pivot coi'ineeting said levers, a thin flat driver blade having a first and a second portion, said portions being disposed at substantially a right angle to each other, the first mentioned portion lying flatwise between the levers at the crossing and being pivotally secured in place between the levers by said pivot for movement independently of each of the levers, and the second mentioned portion being disposed fiatwise between the jaw portions of the levers and at its distal end adapted to enter the kerf of a screw.

In testimony whereof we afiix our signatures in presence of two witnesses.
